圧制御装置。 A manual valve for selecting an oil path by a selection operation, a shift valve connected to the manual valve by a travel range pressure oil path, and a fastening element connected to the shift valve by a fastening pressure oil path. ,
During a selection operation from a stop range position to a travel range position, pressurized hydraulic oil is supplied to the engagement element by passing a shift valve from a different port position where the travel range pressure oil passage and the engagement pressure oil passage are connected. In the hydraulic control device for an automatic transmission according to the present invention, a port bypass oil passage is provided that directly connects the travel range pressure oil passage and the engagement pressure oil passage without using a shift valve,
A hydraulic control device for an automatic transmission, characterized in that a one-way valve is provided in the middle of the port bypass oil passage to shut off when pressurized hydraulic oil is supplied and to allow flow when pressurized hydraulic oil is drained.
